A Time-Dependent Spectral Analysis of $γ$ Cassiopeiae

Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, David P. Huenemoerder, José M. Torrejón, Dustin K. Swarm, Joy S. Nichols | Summary: We investigated the temporal and spectral features of $gamma$ Cassiopeiae’s X-ray emission within the context of the white dwarf accretion hypothesis. We find that the variabilities present in the […]

A Time-Dependent Spectral Analysis of $γ$ Cassiopeiae

Kavli Affiliate: Moritz Guenther | Summary:We investigated the temporal and spectral features of $γ$ Cassiopeiae’s X-ray emission within the context of the white dwarf accretion hypothesis. We find that the variabilities present in the X-ray data show two different signals, one primarily due to absorption and the other due to flickering like in non-magnetic cataclysmic […]

Fault-tolerant quantum computation with a neutral atom processor

Kavli Affiliate: Michael McDonald | Summary:Quantum computing experiments are transitioning from running on physical qubits to using encoded, logical qubits. Fault-tolerant computation can identify and correct errors, and has the potential to enable the dramatically reduced logical error rates required for valuable algorithms. However, it requires flexible control of high-fidelity operations performed on large numbers […]

Beyond Coleman’s Instantons

Kavli Affiliate: Misao Sasaki | Summary:In the absence of gravity, Coleman’s theorem states that the $O(4)$-symmetric instanton solution, which is regular at the origin and exponentially decays at infinity, gives the lowest action. Perturbatively, this implies that any small deformation from $O(4)$-symmetry gives a larger action. In this letter we investigate the possibility of extending […]

Accuracy of Stellar Mass-to-light Ratios of Nearby Galaxies in the Near-Infrared

Kavli Affiliate: Luis C. Ho | First 5 Authors: Taehyun Kim, Minjin Kim, Luis C. Ho, Yang A. Li, Woong-Seob Jeong | Summary: Future satellite missions are expected to perform all-sky surveys, thus providing the entire sky near-infrared spectral data and consequently opening a new window to investigate the evolution of galaxies. Specifically, the infrared […]

Wireless Resource Allocation with Collaborative Distributed and Centralized DRL under Control Channel Attacks

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Wanchun Liu, Teng Joon Lim, , | Summary: In this paper, we consider a wireless resource allocation problem in a cyber-physical system (CPS) where the control channel, carrying resource allocation commands, is subjected to denial-of-service (DoS) attacks. We propose a novel concept of collaborative distributed […]
